3 Why is NASA testing Artemis suits underwater with air lines? Don't the suits need self-contained oxygen to function in space?

Maybe because the water will make it blindingly obvious if there's any leaks or other major problems with the suit?
Vacuum is not liquid.
They could do the exact same in a vacuum chamber or gas pressure chamber.
Micro-gravity simulation my arse.
A swimming pool is a lot easier on the budget than a swimming pool-sized vacuum chamber, you know.
Yes, and water at atmospheric pressure does not act like vacuum.
And water doesn't act like "micro gravity" and water resistance is not the same as zero resistance in vacuum.
This is all theatre and bullshit
Stop being reasonable!
